Whilst studying many fonts with Cyrillic support it became apparent that many fonts do Localisation for Bulgarian Cyrillic and Macedonian/Serbian Cyrillic by using Stylistic Alternates insead of or as well as Open Type Localisation.

The reason which was stated was that Localisation doesn't work in many circumstances and with a lot of software.

I must admit that when I have produced a font I only test the Localisation features very superficially because it is difficult to test.

Does anyone have any experience or information about the Open Type Localisation not working.

Thank you Erwin, I have verified that the localisation works on Kelvinch but I had a wierd e-mail in very bad english from this guy who said that the Serbian localisation didn't work.

Here was me naïvely thinking that this was a function of the operating system and so it would just work based on the location set in the operating system, it seems it is a function of the individual applications.

From now on I will put Localisation in as Stylistic Alternates as well as Open Type Localisation. After all the look up tables already exist so it wouldn't enlarge the font file by very much to use the same lookups in two features rather than just one. And at some point in the future there will be applications which actually use this feature.
